  • Publication number: 20210117943
    Abstract: In a customer transaction system, when a customer terminal device transmits a withdrawal transaction request to a management device, the management device performs a withdrawal transaction request to a financial system server and deducts a withdrawal amount from an account balance. The management device sets, on an automatic teller machine, a withdrawal limit based on the withdrawal amount, generates a withdrawal code and notifies a customer terminal device of the withdrawal code. When the customer terminal device with the withdrawal code being displayed on a display unit is held over the automatic teller machine, the automatic teller machine reads the withdrawal code, makes a withdrawal execution request to the management device, and performs withdrawal based on the withdrawal limit upon receiving withdrawal approval from the management device.
